  名称：

  Synthesis of nickel(II) complexes containing neutral N,N− and anionic N,O− bidentate ligands, and their behaviour as chain-growth catalysts; structural characterisation of complexes containing (mim)2CO, , and mimCPh2O− (mim=1-methylimidazol-2-yl)

  摘要：

  The complexes NiBr2(L-2) [L-2 = (mim)(2)CO (7a), (bim)(2)CO (7b), py(mim)CO (8), PhN=CHbim (9)], NiBr(o-Tol){(mim)(2)CO) (10), Ni(L-2)(o-Tol)(PPh3) [L-2 = mimCO(2)(-) (11a), bmCO(2)(-)(11b), mimCPh(2)O(-) (12), mimC(6)H(4)O(-) (13)], and [Nif(MiM)2C0h1[BF412.0.25H,O (16) have been synthesised from nickel(II) salts (7-9, 16) or NiBr(o-Tol)(PPh3)(2) [10-13], where mim = 1-methylimidazol-2-yl, bim = 1-benzylimidazol-2-yl, and py = pyridin-2-yl. The square-planar complexes (11a, 12) and octahedral 16 have been characterised by X-ray diffraction studies, together with octahedral cis-[Ni(mim)(2)CO)(2)Br(OH2)](BrCD3CN)-C-. (14) and cis-[Ni{(mim)(2)CO}(2)(OH2)(2)Br(2)(.)3CD(3)CN (15). Preliminary catalytic studies have been undertaken with a number of the nickel complexes. Complexes 11-13 form single component catalysts for the oligomerization or polymerization of ethylene and the bromo-complexes (7-9) form active catalysts for the oligomerization or polymerization of ethylene when activated with MMAO.
